1、Designation: A335/A335M 10bStandard Specification forSeamless Ferritic Alloy-Steel Pipe for High-TemperatureService1This standard is issued under the fixed designation A335/A335M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the

2、 year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification2covers n

3、ominal wall and minimumwall seamless ferritic alloy-steel pipe intended for high-temperature service. Pipe ordered to this specification shall besuitable for bending, flanging (vanstoning), and similar form-ing operations, and for fusion welding. Selection will dependupon design, service conditions,

4、 mechanical properties, andhigh-temperature characteristics.1.2 Several grades of ferritic steels (see Note 1) are covered.Their compositions are given in Table 1.NOTE 1Ferritic steels in this specification are defined as low- andintermediate-alloy steels containing up to and including 10 % chromium

5、.1.3 Supplementary requirements (S1 to S7) of an optionalnature are provided. These supplementary requirements call foradditional tests to be made, and when desired, shall be so statedin the order together with the number of such tests required.1.4 The values stated in either SI units or inch-pound

6、unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem may not be exact equivalents; therefore, each systemshall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with th

7、estandard. The inch-pound units shall apply unless the “M”designation of this specification is specified in the order.NOTE 2The dimensionless designator NPS (nominal pipe size) hasbeen substituted in this standard for such traditional terms as “nominaldiameter,” “size,” and “nominal size.”2.

Workmanship, Finish, and Appearance7.1 The pipe manufacturer shall explore a sufficient numberof visual surface imperfections to provide reasonable assurancethat they have been properly evaluated with respect to

41、 depth.Exploration of all surface imperfections is not required but maybe necessary to ensure compliance with 7.27.2 Surface imperfections that penetrate more than 1212 %of the nominal wall thickness or encroach on the minimumwall thickness shall be considered defects. Pipe with suchdefects shall be

42、 given one of the following dispositions:7.2.1 The defect may be removed by grinding provided thatthe remaining wall thickness is within specified limits.7.2.2 Repaired in accordance with the repair welding pro-visions of 7.6.7.2.3 The section of pipe containing the defect may be cutoff within the l

43、imits of requirements on length.7.2.4 Rejected.7.3 To provide a workmanlike finish and basis for evaluat-ing conformance with 7.2, the pipe manufacturer shall removeby grinding the following:7.3.1 Mechanical marks, abrasions (see Note 5) and pits,any of which imperfections are deeper than116 in. 1.6

44、 mm.NOTE 5Marks and abrasions are defined as cable marks, dinges, guidemarks, roll marks, ball scratches, scores, die marks, and the like.7.3.2 Visual imperfections, commonly referred to as scabs,seams, laps, tears, or slivers, found by exploration in accor-dance with 7.1 to be deeper than 5 % of th

45、e nominal wallthickness.7.4 At the purchasers discretion, pipe shall be subject torejection if surface imperfections acceptable under 7.2 are notscattered, but appear over a large area in excess of what isconsidered a workmanlike finish. Disposition of such pipe shallbe a matter of agreement between

46、 the manufacturer and thepurchaser.7.5 When imperfections or defects are removed by grinding,a smooth curved surface shall be maintained, and the wallthickness shall not be decreased below that permitted by thisspecification. The outside diameter at the point of grinding maybe reduced by the amount

47、so removed.7.5.1 Wall thickness measurements shall be made with amechanical caliper or with a properly calibrated nondestructivetesting device of appropriate accuracy. In case of dispute, themeasurement determined by use of the mechanical caliper shallgovern.7.6 Weld repair shall be permitted only s
